Banner SureCross DX80 Wireless Networks - Manual (Page 68)

A link timeout is a failure in the radio communications between the Gateway and a Node. A link is timed out when the Gateway has polled
a Node and failed Maximum Bad Count times consecutively. In the sample shown, the Gateway must poll and fail to communicate with a
Node seven times before the link is considered to be timed out.
A radio link is recovered when the Gateway polls and successfully communicates with the failed Node Re-link Count times before the
Max Bad Count is reached. Successful communications do not have to be consecutive to reach the Re-link count number.
Set the Default Output Conditions checkboxes to establish when the default output conditions are applied.
• Auto-Recover. Selecting the auto-recover option forces the Gateway to attempt to re-establish communications with out-of-sync no-
des after a polling error condition is indicated. The Gateway polls the failed Node and must successfully communicate with the Node
Re-Link Count times before the error condition is erased. This parameter is only used on the Gateway. Without the auto-recover
feature selected, the user must manually reset error conditions or the host system must reset the error condition.
• Gateway Link Failure. The Gateway detected an RF communication problem with a Node. All outputs on other devices that are linked
to inputs on the failed device are set to the default states.
• Host Link Failure. A Modbus timeout forces all device outputs to the default states. This parameter applies to every device that sets
this flag.
• Node Link Failure. A Node detected an RF link problem and set its own outputs to the default states.
• Out of Sync. When an out-of-sync condition is detected, all Node outputs are set to the default value. This parameter applies only to
the Nodes.
• Power Up. All device outputs are set to the default value on initial power-up.
In the sample shown, the default output conditions are applied when the Gateway detects the failed link and when the Node detects the
failed link. Also selected is the auto-recovery option.
To decrease the time to determine a link timeout, decrease the Polling Interval. Reducing the Max Bad Count parameter will also detect a
link failure quicker, but will potentially cause more false time-out conditions.
To increase the time to determine a link timeout, increase the Polling Interval or the Max Bad Count. For radio networks extended to the
limits of the transmission range, increasing the Max Bad Count may help reduce the link timeout errors.

System Network Settings
Using the System > Setup > Network screen, set up the DX80 device by defining the IP address, subnet mask, and gateway. Click on the
Change IP button and reboot the system for the new IP settings to take effect.
